No, no, no. That is a parallel connection. For two 6V batteries, you have to connect + (on battery 1) to - (on battery 2) then connect the charger to the - (on battery 1) and the + (on battery 2).

That is, if you are charging them with a 12V charger.

You do not want to charge a single 6V battery with a 12V charger.

Also note, a fully charged automotive battery contains 2.5V per cell. If you measure the voltage on a fully charged battery not connected to the electrical system, it should measure 15V.
